SeVen The switchyard is esigned using a breaker and-a-half scheme. The switchyard currently has connections 'with the CPCL transmission network; each of these transmission lines is physically indepencfent. The switchyard has ane connection with each of the two Startup Auxiliary Transforiers and each SAT can be fed directly from an associated offsite transmission line. The Startup Auxiliary Transformers are the preferred power source far the Class 1E ESF buses. The minimum alignment of affsite power sources will be maintained such that at least two physically independent offsite circuits are available. The two physi-cally independent circuits may consist of any two af'he incoming transmission lines to the SATs (either thraugh the switchyarct ar directly) and into the Class 1E system. As Iong as there are at least two transmission lines in ser vice and twa circuits through the SATs to the Class 1E buses, the LCQ is met. Ouring MOOES 5 and 6, the C1ass lE buses can be energized fram the offsite transmissian net work via a combination of the main transformers, and unit, auxiliary transformers.

These requirements allow a period of time to restore any required feature discovered to be inoperable, e.g. out-of-service for maintenance, to an OPERABLE status. If the required feature(s) cannot be restored to in OPERABLE status, the ACTION statement requires the redundant required feature, i.e. feature receiving power from an inoperable A.C. source, to be declared inoperable and a controlled plant shutdown performed. The allowed operating times to restore an inoperable required feature to an OPERABLE status is based on the requirements in NUREG 1431.

INSERT 13 to Page B 3/4 8-2: Table 4.8-1, Diesel Generator Test Schedule, allows each diesel generator to be tested on a staggered test basis at a maximum interval of every 31 days when the number of valid failures in the last 25 valid tests on each diesel generator as defined by Regulatory Guide 1.9 Revision 3 is 3 or less. The test schedule requires the frequency of testing be reduced to an interval of no less than 24 hours nor more than the 7 days when either diesel generator has experienced 4 or more valid failures in the last 25 tests. Furthermore, this schedule requires the reduced time frequency to be maintained until completion of 7 consecutive valid tests. In addition, should any operation of the diesel generator result in a valid failure as defined in Regulatory Guide 1.9 Revision 3 during the reduced test frequency period and the number of valid failures is 4 or more, testing at the reduced frequency interval shall continue until completion of 7 valid failure-free tests. This test schedule implements the recommendations of Generic Letter 84-15, NUREG/CR-5057 (Recommended Practice for Aging Mitigation and Improved Programs for Nuclear Service Diesel Generators). Should more than 3 valid failures occur within the last 25 valid tests, then there is probable cause that diesel generator degradation may have occurred and the failure events are not due to a series of random events. Reducing the test frequency provides for timely accumulation of data. The requirement to complete 7 valid tests provides reasonable assurance that the corrective action(s)'aken were appropriate and diesel generator reliability is restored to a level that allows return to a 31 day or less interval test schedule.

-.3 4.8 ELECTRICAL POW YSTEMS l BASES 3 4.8. 1 3 4.8.2 AND 3 4.8.3 A.C. SOURCES D.C. SOURCES AND ONSITE POWER D B 0 The OPERABILITY of the A.C. and D.C power sources and associated distribution systems during operation ensures that sufficient power will be available to supply the saf'ety-related equipment required for: (1) the safe shutdown of the facility, and (2f the mitigation and control of accident conditions within the facility. The minimum specified independent and redundant A.C. and D.C. ower sources and distribution systems satisfy the requirements of General esign Criterion 17 of Appendix A to 10 CFR Part 50. The switchyard is designed using a breaker-and-a-half scheme. The switchyard currently has seven connections with the CP8L transmission network; each of these transmission lines is physically independent. The switchyard has one connection with each of the two Startup Auxiliary Transformers and each SAT can be fed directly from an associated offsite transmission line. The Startup Auxiliary Transformers are the preferred power source for the Class lE ESF buses. The minimum alignment of offsite power sources will be maintained such that at least two physically independent offsite circuits are available. The two physically independent circuits may consist of any two of the incoming transmission lines to the SATs (either through the switchyard or directly) and into the Class 1E system. As long as there are at least two transmission lines in service and two circuits through the SATs to the Class lE buses, the LCO is met. During NODES 5 and 6 the Class 1E buses can be energized from the offsite transmission net work via a combination of the main transformers, and unit auxiliary transformers. This arrangement may be used to satisfy the requirement of one physically independent circuit. The ACTION requirements specified for the levels of degradation of the power sources provide restriction upon continued facility operation commensurate with the level of degradation. The OPERABILITY of the power sources are consistent with the initial condition assumptions of the safety analyses and are based upon maintaining at least one redundant set of onsite A.C. and D.C; power sources and associated distribution systems OPERABLE during accident conditions coincident with an assumed loss-of-offsite power and single failure of the other onsite A.C. source. The A.C. and D.C. source allowable out-of-service times are based on Regulatory Guide 1.93, "Availability of Electrical..Power Sources," December 1974. There are additional ACTION requirements to verify that all required feature(s) that depend on the remaining OPERABLE A.C. sources as a source of emergency

power, are also OPERABLE.

These requirements allow a period of time to restore any required feature discovered to be inoperable, e.g. out-of-service for maintenance, to an OPERABLE status. If the required feature(s) cannot be restored to an OPERABLE status, the ACTION statement requires the redundant required feature, i.e. feature receiving power from an inoperable A.C. source, to be declared inoperable and a controlled plant shutdown performed. The allowed operating times to restore an inoperable required feature to an OPERABLE status is based on the requirements in NUREG 1431. The term "verify", as used in these ACTION statements means to administratively check by examining logs or other information to determine the OPERABILITY of required feature(s). It does not mean to perform the Surveillance Requirement needed to demonstrate the OPERABILITY of the required feature(s). SHEARON HARRIS - UNIT 1 B 3/4 8-1 Amendment No.

ELECTRICAL POWER SYSTEii BASES A.C. SOURCES D.C. SOURCES AND ONSITE POWER DISTRIBUTION Continued The OPERABILITY of the minimum specified A.C. and D.C. power sources and associated distribution systems during shutdown and refuelinq ensures that: (1) the facility can be maintained in the shutdown or refueling condition for extended time periods and (2) sufficient instrumentation and control capability is availab/e for monitoring and maintaining the unit status. The Surveillance Requirements for demonstrating the OPERABILITY of the diesel generators are based upon the recommendations of Regulatory Guides 1.9, Selection of Diesel Generator Set Capacity for Standby Power Supplies," December 1979; 1.108, "Periodic Testing of Diesel Generator Units Used as Onsite Electric Power Systems at Nuclear Power Plants," Revision 1, August 1977 as modified in accordance with the guidance of IE Notice 85-32, April 22, 1985; and 1.137, "Fuel-Oil Systems for Standby Diesel Generators," Revision 1, October 1979. The inclusion of the loss of generator potential transformer circuit lockout trip is a design feature based upon coincident logic and is an anticipatory trip prior to diesel generator overspeed. Table 4.8-1, Diesel Generator Test Schedule, allows each diesel generator to be tested on a staggered test basis at a maximum interval of every 31 days when the number of valid failures in the last 25 valid tests on each diesel generator as defined by Regulatory Guide 1.9 Revision 3 is 3 or less. The test schedule requires the frequency of testing be reduced to an interval of no less than 24 hours nor more than the 7 days when either diesel generator has experienced 4 or more valid failures in the last 25 tests. Furthermore, this schedule requires the reduced time frequency to be maintained until completion of 7 consecutive valid tests. In addition, should any operation of the diesel generator result in a valid failure as defined in Regulatory Guide 1.9 Revision 3 during the reduced test frequency period and the number of valid failures is 4 or more, testing at the reduced frequency interval shall continue until completion of 7 valid failure-free tests. This test schedule implements the recommendations of Generic Letter 84-15, NUREG/CR-5057 ~ ~ ~ ~ Recommended Practice for Aging Mitigation and Improved Programs for Nuclear ervice Diesel Generators). Should more than 3 valid failures occur within the last 25 valid tests, then there is probable cause that diesel generator degradation may have occurred and the failure events are not due to a series of random events. Reducing the test frequency provides for timely accumulation of data. The requirement to complete 7 valid tests provides reasonable assurance that the corrective action(s) taken were appropriate and diesel generator reliability is restored to a level that allows return to a 31 day or less interval test schedule. The Surveillance Requirement for demonstrating the OPERABILITY of the station batteries are based on the recommendations of Regulatory Guide 1. 129, "Haintenance Testing and Replacement of Large Lead Storage Batteries for Nuclear Power Plants," February

1978, and IEEE Std 450-1980, "IEEE Recommended Practice for Haintenance,
Testing, and Replacement of Large Lead Storage Batteries for Generating Stations and Substations."

Yerifying average electrolyte temperature above the minimum for which the battery was sized, total battery terminal voltage on float charge, connection resistance

values, and the performance of battery service and discharge tests ensures the effectiveness of the charging system, the ability to handle high discharge rates, and compares the battery capacity at that time with the rated capacity.

ELECTRICAL POWER SYSTEI BASES A.C. SOURCES D.C. SOURCES AND ONSITE POWER DISTRIBUTION Continued " Table 4.8-2 specifies the normal limits for each designated pilot cell and each connected cell for electrolyte level, float voltage, and specific gravity. The limits for the designated pilot cells float voltage and specific gravity, greater than 2. 13 volts and 0.015 below the manufacturer's ful1 charge specific gravity or a battery charger current that had stabilized at a low value, is characteristic of a charged cell with adequate capacity. The normal limits for each connected cell for float voltage and specific gravity, greater than 2.13 volts and not more than 0.020 below the manufacturer's full charge specific gravity with an average specific gravity of all the connected cells not more than 0.010 below the manufacturer's full charge specific gravity, ensures the OPERABILITY and capability of the battery. Operation with a battery cell's parameter outside the normal limit but within'the allowable value specified in Table 4.8-2 is permitted for up to 7 days. During this 7-day period: (1) the allowable values for electrolyte level ensures no physical damage to the plates with an adequate electron transfer capability; (2) the allowable value for the average, specific gravity of all the cells, not more than 0.020 below the manufacturer's recommended full charge specific gravity, ensures that the decrease in rating will be less'than the safety margin provided in sizing; (3) the allowable value for an individual cell's specific gravity, ensures that an individual cell's specific gravity will not be more than 0.040 below the manufacturer's full charge specific gravity and that the overall ca ability of the battery will be maintained within an acceptable limit; and 4 the allowable value for an individual cell's float voltage, greater than 7 volts, ensures the battery's capability to perform its design function. 3 4.8.4 ELECTRICAL E UIPMENT PROTECTIVE DEVICES Containment electrical penetrations and penetration conductors are protected by either deenergizing circuits not required during reactor operation or by demonstrating the OPERABILITY of primary and backup overcurrent protection circuit breakers during periodic surveillance. The Surveillance Requirements applicable to lower voltage circuit breakers provide assurance of breaker reliability by testing at least one representative sample of each manufacturer's brand of circuit breaker. Each manufacturer's molded case and metal case circuit breakers are grouped into representative samples which are then tested on a rotatinq basis to ensure that all breakers are tested. If a wide variety exists within any manufacturer's brand of circuit breakers, it is necessary to divide that manufacturer's breakers into groups and treat each group as a separate type of breaker for surveillance purposes. The bypassing of the motor-operated valves thermal overload protection during accident conditions by integral bypass devices ensures that safety-related valves will not be prevented from performing their function. The Surveillance Requirements for demonstrating the bypassing of the thermal overload protection during accident conditions are in accordance with Regulatory Guide 1.106 "Thermal Overload Protection for Electric Motors on Motor Operated Valves," Revision 1, March 1977.
